Stream Corridor Restoration


Book Description

This document is a cooperative effort among fifteen Federal agencies and partners to produce a common reference on stream corridor restoration. It responds to a growing national and international interest in restoring stream corridors.




Riparian Areas


Book Description

The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.




Environmentally Sensitive Channel- and Bank-protection Measures


Book Description

TRB's National Cooperative Highway Research Program (NCHRP) Report 544: Environmentally Sensitive Channel- and Bank-Protection Measures examines environmentally sensitive channel- and bank-protection measures and includes recommended design guidelines for their application and a selection system for helping to determine the most appropriate channel- and bank-protection measure. The selection system is presented as an interactive software program entitled "Greenbank," which can be found on the accompanying CD-ROM (CRP-CD-58). The selection system software (CRP-CD-58) is available for download in an ZIP format.

Aquatic Habitat Assessment


Book Description

Abstract: Habitat is now the basis of most impact assessments and resource inventories, and it is the basis of many species management plans, mitigation planning, and environmental regulation. Habitats are relatively stable through time, easily defined in intuitive physical terms, and provide a tangible resource for negotiations and decision making. Numerous and varied methods of analyzing and reporting habitat conditions have been developed by federal, state, provincial, and private agencies. Habitat assessment approaches vary greatly among regions of the continent. The great variability in methods and an unusually wide range of practices have impeded the ability of agencies to share and synthesize information. A diversity of methods is desirable in the initial stages of a rapidly developing field, but enough time has passed to assess the state-of-knowledge and identify the best of the currently used methods and techniques. This manual is intended to provide fisheries biologists with a limited set of techniques for obtaining aquatic habitat data. The manual also describes the range of information collected and used in agency habitat analyses. Agencies planning habitat programs should review the synthesis of established and documented methods being used in North America (Appendix 1) and the planning recommendations in Chapter 2. Then, the remaining chapters should be reviewed to determine what types of habitat data should be included in the agency's program.




Biotechnical and Soil Bioengineering Slope Stabilization


Book Description

The first comprehensive, practical guide to the selection,construction, and installation of soil bioengineering andbiotechnical slope protection Here is the ultimate guide to physically attractive,environmentally compatible, and cost-effective methods ofprotecting slopes from erosion and mass wasting. Lavishlyillustrated with more than 150 photographs and supplemented withscores of charts and tables, this book covers the entire subjectfrom general principles and background on the nature of soilerosion and mass movement to detailed information on rootstrengths, treatment selection, unit costs, critical tractivestresses, methods for harvesting and handling live cuttings, andmore. Four illustrated case studies, each addressing a different set ofproblems and solutions, demonstrate both the application ofparticular technologies and the site investigation, planning,scheduling, and organization required to complete these projectssuccessfully. This unique reference handbook * Reviews the horticultural and engineering underpinnings forbiotechnical and soil engineering treatments * Documents and explains the role of woody plants in stabilizingslopes against both surficial erosion and mass movement * Provides details on a broad range of soil bioengineering methods,including live staking, live fascines, brushlayering, live cribwalls, branchpacking, and live slope gratings * Describes various biotechnical methods and materials, includingthe incorporation of vegetation in erosion control blankets,flexible mats, cellular revetments (geocells), rock armor (riprap), and gabion and open-front crib walls * Summarizes the findings of the National ScienceFoundation-sponsored workshop to assess the state of the art anddetermine research needs For practicing professionals, researchers, and students ingeotechnical engineering, geology, soil science, forestry andforest engineering, landscape architecture, environmentalhorticulture, and restoration ecology, this book offers thorough,up-to-date coverage that is not available from any other singlesource.
